July 19 (UPI) -- The Iranian government on Friday disputed a claim by the United States that the American Navy shot down an Iranian drone in the Strait of Hormuz -- a position that again brought a steely warning from U.S. President Donald Trump.

Friday, he again insisted the drone was destroyed -- and issued another stern warning to Tehran.

"We have the greatest ships -- the most deadly ships, we don't want to have to use them," he told reporters at the White House. "We hope for their sake they don't do anything foolish. If they do, they will pay a price like nobody's ever paid."

National security adviser John Bolton said there's "no question" the drone taken by the USS Boxer belonged to Iran, and said it posed a threat.

Iran shot down a U.S. drone in the region last month, and the United States retaliated by imposing new economic sanctions. Those moves followed multiple attacks that targeted oil tankers in the Gulf of Oman, for which U.S. officials blamed Tehran.

"Unlike Trump's delusional and groundless claim, all drones belonging to the Islamic Republic of Iran in the Persian Gulf and the Strait of Hormuz, including the one mentioned by the U.S. president, have returned to their bases safe and sound after carrying out their scheduled surveillance and control operations," Shekarchi said.

Araqchi suggested a possibility in which the Navy shot down a U.S. drone by mistake.

Later Friday, Iran aired video footage on state television it said proved the downed drone belonged to the United States.
